74AHCT244PW,112

Buffers, Drivers, Receivers, Transceivers Overview

The Nexperia 74AHCT244PW,112 is an octal buffer and line driver featuring three-state outputs. It operates within a supply voltage range of 4.5 V to 5.5 V and accepts TTL input levels. The device provides balanced propagation delays and includes Schmitt-trigger action on all inputs for noise immunity. It supports ambient temperatures from -40 °C to +125 °C and utilizes a TSSOP20 package.

Buffers, Drivers, Receivers, Transceivers Feature Summary

• Features two independent output enable controls (1OE and 2OE), each managing four three-state outputs.
• Inputs are overvoltage tolerant up to 5.5 V, enabling use as translators in mixed-voltage environments.
• All inputs incorporate Schmitt-trigger action to ensure high noise immunity.

Buffers, Drivers, Receivers, Transceivers Applications

• Translating signals between mixed voltage logic environments
• Driving bus lines with three-state capability
• Buffering data lines in digital systems

Buffers, Drivers, Receivers, Transceivers Procurement Notes

Verify the specific ordering suffix against current Nexperia documentation to confirm package type and temperature range. Confirm availability status as distribution channels may list end-of-life or discontinued items. Ensure the selected variant matches the required operating conditions and pinout configuration for the target application design.

Buffers, Drivers, Receivers, Transceivers Selection Notes

Select this component when TTL-compatible inputs are required alongside CMOS performance characteristics. The AHCT series ensures compatibility with standard TTL logic levels while maintaining low power dissipation. Verify that the TSSOP20 package dimensions fit the PCB layout constraints and thermal requirements of the system design.

Buffers, Drivers, Receivers, Transceivers Part Context

This part belongs to the 74AHC/AHCT logic family, which combines high-speed CMOS technology with TTL-compatible input levels. The 74AHCT244 specifically serves as an octal buffer/line driver. It is distinct from the 74AHC244, which accepts CMOS input levels, and other variants like the automotive-qualified 74AHC244PW-Q100.
